Objective To develop the clinical application and the method for functional repair in fa- cial nerve defect in parotideetomy of parotid carainoma.Methods Defect of facial nerve in parotidectomy was repaired by transplantation of sternocleidomastoid muscle-great auricular nerve flap with anastomosis of great auricular nerve-facial nerve under microscope.Results Eight eases of facial nerve defect in parotid carcinoma were repaired by this method.The facial nerve function almost recovered and access to normal dur- ing 3 to 6 month after operation in this series.6 of 8 patients achieved a gradeⅡ,2 of 8 patients achieved a gradeⅢ.Conclusion Reconstruction of facial nerve defect using sternocleidomastoid muscle-great auricu- lar nerve flap can provide better blood supply for the plerosis and regeneration of nerve.The nerve flap also ac- celerate the functional recovery after nerve grafting.
5.The design and implementation of real-time MPEG-2 video transmission in telemedicine system.
Chinese Journal of Medical Instrumentation 2002;26(6):427-429
It is particularly important for telediagnosis to transmit diagnostic video in real time. Firstly, we introduce image compression, multithread and multicast technology, then a solution is provided for the real-time video transmission system based on TCP/IP LAN.

Objective To compare the effects on neurobiological factors of attributional retraining group therapy (ARGT) or selective serotonin reuptake inhibitors (SSRI) for major depressive disorder (MDD),anxiety disorder (AD) and obsessive-compulsive disorder (OCD).Methods Outpatients with MDD,AD and OCD were divided into ARGT group (n =63) and SSRI group (n =66) according to the sequence of entering the study.MDD,AD and OCD patients were respectively measured with Hamilton Depression Scale (HAMD),Hamilton Anxiety Scale (HAMA),and Yale-Brown Obsessive Compulsive Scale (Y-BOCS) before and after 8 weeks treatment.All subjects were detected of plasma serotonin,norepinephrine,cortisol and adrenocorticotropic hormone by radioimmunoassay before and after treatment.Results After treatment,HAMD scores of MDD patients were reduced significantly in both ARGT group (t =18.411,P =0.000) and SSRI group (t =20.092,P =0.000) ; HAMA scores of GAD patients were reduced significantly in both ARGT group (t =13.989,P=0.000) and SSRI group (t=15.815,P=0.000) ;Y-BOCS scores of OCD patients were reduced significantly in both ARGT group (t =5.465,P =0.000)and SSRI group (t =4.792,P =0.000).In ARGT group,MDD (t =3.145,P =0.006),AD (t =2.785,P =0.012) and OCD patients (t =2.877,P =0.011) decreased plasma cortisol concentrations significantly.In SSRI group,MDD (t =-2.923,P =0.010) and OCD patients (t =-2.301,P =0.035) improved plasma serotonin significantly and MDD patients (t =-2.333,P =0.033) improved plasma norepinephrine significantly.Conclusion ARGT can modulate plasma cortisol level.SSRI can up-modulate plasma serotonin level.The two therapies take effect by different biological ways.

Objective To discuss the application value of 18F-FDG PET/CT in diagnosis of colorectal cancer. Methods We retrospectively analyzed the data of 186 patients who were diagnosed as colorectal cancer by 18F-FDG PET/CT. We classifed all cases according PET/CT imaging into position group and type group,and calculated SUV (maximum standard uptake value) of tumor tissue, and compared with normal tissue. Results There were 112 cases of rectal cancer,27 cases of carcinoma of sigmoid, 17 cases of carcinoma of cecum,16 cases of ascending colon carcinoma,14 cases of carcinoma of descending colon according to positions via PET/CT. There were 68 cases of protrude type,57 cases of ulcerative type,34 cases of infiltrating type,27 cases of colloid adenoma according types via PET/CT. The SUV of tumor tissue was higher than normal value,the difference had statistical significance. Conclusion 18F-FDG PET/CT has high application value in colorectal cancer diagnosis, positions and types.
